Filed Sept. 17, 1938 2 Sheets-Sheet 2 Patented Jan. 9', 1940 UNITED STATES eATENT arms MILK COOLER Peter R. Yost, Goshen, Ind. Application September 17, 1938, Serial No. 230,477 2 Claims. (01. 257-179) The object of my invention is to provide a novel milk cooler for the use of'mllk producers to cool their milk while it is being strained into the can; to provide novel means for circulating water of a lower temperature than the milk around the neck of the cover, which is mounted in the neck of the can into which the milk is strained and poured; to provide a device of this character which can be manufactured at reasonable cost, and which will be efiicient and easily applied to and removed from the ordinary large milk cans.

I attain these and other objects of my invention by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the invention mounted in a milk can, a portion of the base 20 being shown in section;

Fig. 2 is a vertical section through the invention;

Fig. 3 is a horizontal section on line 3-3 of Fi 2;

Fig. 4 is a top plan view of the cover lil; Fig. 5 is a detail plan View of ring 9; Fig. 6 is a horizontal section on line 6-6 of i Fig. 2;

'member Illa, and

' Fig. 11 is a horizontal section on line I l l l of Fig. 8.

Referring to the accompanying drawings, there is illustrated a conventional large milk can C, having a conventional flared neck it. I provide 'a cylindrical jacket I having an outturned flange 2 to receive the approximately funnel-shaped strainer S, which has a wire sieve or strainer s. I provide an annular bottom member 3 having an upturned flange l engaging the jacket I, and

an upturned flange 5 engaging the lower end of a. corrugated pipe 6, the corrugations of which may be disposed either in a parallel or horizontal direction, or disposed spirally. This corrugated pipe terminates at the top in the lip l, which is engaged by an annular bracket 8 which is shaped to support a rubber ring orgasket 9, on which a perforated plate I is seated, plate H3 which water is supplied to the chamber having. annular spaced perforations l2, and a handle, afioxed to the perforated plate ill. The function of the gasket 9 is to prevent milk from passing around the outer edge and under plate ill,

so that it must pass through the annular spaced perforations l2, whereby to control the amount .of milk passing over the cooling surface the corrugated pipe 6. I provide an inlet tube Iii opening into the'bottom oi the jacket 6 and by I810 which surrounds the jacket l. A suitable outlet l9 opens out of the water space adjacent the upper end of the cooler 45, and a suitable rubber hose 28 may be attached to it, likewise a similar hose 2E1" isattached to the inlet tube I6. The jacket has an annular hollow rib or projection I4 adapted to seat on the flared neck it of the can C to support the cooler jacket in preper position in the mouth. of the milk can, as

shown in Figs. 1 and 2. l

In operationwater is supplied through hose 2t and inlet tube it at the bottom of the cooler jacket and circulates around the cooler coils or corrugated pipes 6 and isdischarged through the outlet tube 19. -This constant circulation of cool Water quickly cools the milkand the device is one that is easily operated.

Referring to Figs. 7-11,'there is illustrated an improved form of my invention having a per-.

forated plate Illa. of convex shape with the spacedv 301 annular perforations l2 laterally the periphery of the plate, the plate being integral with the vertical cylindrical'extension 21 seats Within the cylindrical jacket 5, the member 2i having an annular .outturned flange 22 on which the strainer may seat, as shown in Fig. 8. In this form of the invention, the gasket 9 is eliminated and in. lieu thereof an annular member 9b is provided having its annular bracket or downturned annular flange 8 seated in the upper end of the 14 0 corrugated pipe 6, as shown in Fig. 8, and the upper annular flange of member 912 being positioned between member 24 and member l, as shown in Fig. 8. In other respects the construetion and operation of this form of theinvention is the same as shown in Figs. 1 and 2.

This c'onstructionpermits of greater convenience in cleaning the mechanism and it lets the milk enter at a point where it will run slowly and evenly down over the corrugations to cool.

As shown in the drawings, applicants cooler was purposely made to fit down into the milk can, its weight preventing it from becoming topheavy and upsetting or being knocked over while in use and also avoiding liftingthe milk so high '65 to pour into the cooler as would be necessary with the cooler mounted on top of the can.

What I claim is:

1. In a milk cooler, the combination of a cylindrical jacket of suitable size to be inserted and extending down into the neck of a conventional large milk can, having a projection seating on the flared neck of the milk can, an annular bottom member having spaced upturned flanges, one of the said flanges being secured to the afore said jacket, a corrugated pipe mounted in the aforesaid jacket, a perforated plate seated on the top of the corrugated pipe, an inlet tube opening into the jacket adjacent the upper end of the corrugated pipe and terminating at a point close to the lower end of the corrugated pipe, and an outlet tube in the jacket opposite the inlet tube, each of said tubes being of suitable size for attachment to hose. 7

2. In a milk cooler, the combination of a cylindrical jacket of suitable size to be inserted and extending down into the neck of a conventional large milk can, an annular bottom member having spaced upturned flanges, one of the said flanges being secured to the aforesaid jacket, a corrugated pipe mounted in the aforesaid jacket, an annular bracket mounted on the upper end of said corrugated pipe, a gasket on said bracket, a perforated plate seated on the top of the corrugated pipe, an inlet tube opening into the jacket adjacent the upper end of the corrugated pipe and terminating at a point close to the lower end of the corrugated pipe, and an outlet tube in the jacket opposite the inlet tube, each of said tubes being of suitable size for attachment to hose.
